I'm looking for a developer to build a Delphi application to connect to QuickBooks Payments API using Delphi 10.2 and IP*Works! Auth and IP*Works! components from /n software. The application needs to use OAuth2 to connect to QuickBooks Payments and needs to support following credit card transaction types: authorize, capture, void and credit.
I am very much experience in working with Quickbooks and Delphi. Have developed so many QuickBooks integrator. Have been working with Delphi for the last 19+ years. Also very much experience in IP*Works.
